Description

Returns a data frame of meteorological or hydrological stations with their coordinates in particular year. The returned object is valid only for a given year and type of stations (e.g. "synop", "climate" or "precip"). If add_map = TRUE additional map of downloaded data is added.

Usage

nearest_stations_imgw(
  type = "meteo",
  rank = "synop",
  year = 2018,
  add_map = TRUE,
  point = NULL,
  no_of_stations = 50,
  ...
)

Arguments

type

data name;"meteo" (default), "hydro"

rank

rank of the stations: "synop" (default), "climate", or "precip"; Only valid if type = "meteo

year

select year for serching nearest station

add_map

logical - whether to draw a map for a returned data frame (requires maps/mapdata packages)

point

a vector of two coordinates (longitude, latitude) for a point we want to find nearest stations to (e.g. c(15, 53)); If not provided calculated as a mean longitude and latitude for the entire dataset

no_of_stations

how many nearest stations will be returned from the given geographical coordinates. 50 used by default

...

extra arguments to be provided to the graphics::plot() function (only if add_map = TRUE)

Value

A data.frame with a list of nearest stations. Each row represents metadata for station which collected measurements in a given year. Particular columns contain stations metadata (e.g. station ID, geographical coordinates, official name, distance from a given coordinates).

Examples

# NOT RUN {
  nearest_stations_imgw(type = "hydro", 
  rank="synop",
  year=2018,
  point = c(17, 52),
  add_map = TRUE, 
  no_of_stations = 4)
# }
# NOT RUN {
